Calculate the sound intensity level in decibels from the sound intensity. The decibel scale is logarithmic, meaning small changes in dB represent large changes in intensity.
Enter your values below
Power per unit area of the sound wave
Threshold of hearing: 10⁻¹² W/m² (default)
How this calculator works
Sound intensity level equals 10 times the base-10 logarithm of intensity divided by the reference intensity I₀ = 10⁻¹² W/m². Measured in decibels (dB).
